We determined the relative effectiveness of different areas of the visual field in determining the perceptual upright. The perceptual upright was measured using the character 'p', the identity of which depended on its perceived orientation (the Oriented Character Recognition Test). The visual field was divided into left and right, upper and lower, and central and peripheral halves, with different backgrounds presented in each area. The left and right visual fields contributed equally to the perceptual upright while the lower visual field demonstrated a larger effect on the perceptual upright as compared to the upper visual field. The central and peripheral visual fields interacted with one another in a complex manner, although a separate experiment suggested that the peripheral visual field did not alter the perceived orientation of the central field.
我们确定了视野不同区域在确定感知垂直方向方面的相对有效性。使用字母“p”来测量感知垂直方向，其识别取决于其感知到的方向（定向字符识别测试）。视野被分为左半部分和右半部分、上半部分和下半部分以及中央部分和周边部分，每个区域呈现不同的背景。左视野和右视野对感知垂直方向的贡献相同，而下视野与上视野相比，对感知垂直方向的影响更大。中央视野和周边视野以复杂的方式相互作用，尽管一项单独的实验表明周边视野不会改变中央视野的感知方向。
